Removing an implant abutment screw can be a challenging task, especially when the screw is stripped or broken. This article provides a comprehensive guide on various methods and techniques to successfully remove an implant abutment screw, along with visual aids and videos to enhance understanding.
Implant abutment screws play a crucial role in dental implants as they connect the abutment to the implant fixture. Over time, these screws can become loose or fractured due to various factors such as improper torque during placement, material fatigue, or even occlusal overload.
- Loosening: Often occurs due to inadequate torque or changes in occlusion.
- Fracture: Can happen if excessive force is applied or if the screw material weakens over time.
- Stripping: Results from using the wrong tool or applying too much torque.
Understanding these issues is vital for effective management and removal of abutment screws.
Before attempting to remove an abutment screw, it is essential to gather the necessary tools:
- Screw Removal Kit: Typically includes various drill bits and drivers specifically designed for screw extraction.
- Handpiece: For drilling and engaging with the screw.
- Irrigation System: To cool the area during drilling, preventing overheating.
- Tweezers or Needle Holders: For grasping small fragments of the screw.
- Cotton Swabs and Adhesive Micro-applicators: For cleaning and assisting in removal.
There are several methods for removing an implant abutment screw, depending on the condition of the screw (loose, fractured, or stripped).
1. Identify the Type of Screw Damage:
- If the screw is loose but intact, simply use a driver to unscrew it.
- If it's stripped or broken, proceed with specialized tools.
2. Engage the Screw:
- Use a claw driver in a counterclockwise rotation at 30-50 RPM to engage the top surface of the broken screw.
3. Drill Technique:
- If engagement is unsuccessful, use a drill at 1500-200 RPM to create a crevice that allows better grip for removal.
4. Final Extraction:
- Once sufficient grip is established, remove the screw using tweezers or a needle holder.
A dedicated screw removal kit is essential for this process. These kits often come with various tools tailored for different types of screws and situations.
1. Assess the Situation:
- If part of the screw is still accessible, you can use reverse drilling techniques.
2. Drill into the Screw:
- Use a reverse drill bit suitable for your implant size and set your handpiece to reverse mode at about 2000 RPM. Drill into the screw fragment carefully.
3. Remove with Driver:
- After drilling, use an appropriate driver to back out the screw fragment.
Reverse drilling can be particularly effective when dealing with broken screws that have no visible head left for engagement.
1. Create a Slot in the Screw Head:
- If the head of the screw is stripped, use a small burr to carve a slot into it.
2. Use Flat Tip Driver:
- Insert a flat tip driver into the slot and turn counterclockwise to remove it.
This method allows for better engagement with stripped screws and can be performed relatively quickly with minimal risk of damaging surrounding structures.
When removing an implant abutment screw, there are several additional considerations that practitioners should keep in mind:
Ensuring patient comfort during this procedure is paramount. Use local anesthesia if necessary and communicate clearly with your patient about what to expect during the procedure.
Maintain strict infection control protocols throughout the process. This includes using sterile instruments and ensuring that the surgical field remains clean.
After successful removal of the screw, assess the site for any potential complications such as infection or damage to surrounding tissues. Provide appropriate follow-up care instructions to your patient.

Removing an implant abutment screw requires precision and appropriate tools. Understanding the condition of the screw and employing suitable methods can help ensure successful removal without damaging the implant. Always prioritize patient safety and comfort during these procedures.
By following these guidelines and utilizing proper techniques, dental professionals can effectively manage complications arising from implant abutment screws, thereby maintaining optimal patient outcomes.
If your abutment screw is stripped, you can create a slot in its head using a burr and then use a flat tip driver to back it out.
Yes, using specialized tools like reverse drills and proper technique can help you remove broken screws while minimizing damage to the implant.
Abutment screws should be checked regularly during dental visits, especially if there are signs of loosening or discomfort.
Common causes include improper torque application during placement, material fatigue over time, and excessive occlusal forces.
No, it is not advisable to attempt removing an abutment screw at home; this should be done by a qualified dental professional.
